Write SwiftUI on your phone, watch it run, and paste it into Xcode. Swoop is a canvas for postcard-sized components. Type one, press play, and it runs for real — springs, timing and trigonometry computed on the device at the frame rate you feel. Copy hands back plain SwiftUI that compiles. Most SwiftUI apps are catalogues you browse. This is the one where you write it. WHAT IT PLAYS Swoop runs a documented subset of SwiftUI, on device. • Text, Image, Button, Toggle, Spacer, Divider • VStack, HStack, ZStack, ForEach, TimelineView • Circle, Capsule, Rectangle, RoundedRectangle • frame, padding, offset, opacity, scaleEffect, rotationEffect, zIndex • fill, stroke, trim, background, overlay, clipShape, shadow • animation, onAppear, symbolEffect, sensoryFeedback • @State, helper funcs, computed views, if/else, ranges • sin, cos, tan, sqrt, pow, min, max, .pi If Swoop cannot play something exactly the way Xcode would, it refuses and points at the line rather than guessing. What you copy always compiles. Swoop is for one component at postcard size — not for building whole screens on a phone. ScrollView, List, NavigationStack, GeometryReader and TextField are deliberately not included. A REAL EDITOR • Line numbers and syntax colour • Autocorrect, smart quotes and autocapitalisation switched off • Every file in your library previews itself, running, in the list POST IT AND RECORD IT • Publish a component to the community, free, under your username • Anyone can play it and take the source • Record three seconds of it running and share the video • Like and view counts on everything published PRIVACY • Your files are saved on your phone • Nothing is uploaded, read by us, or used to train anything • A file leaves the device only when you publish or share it • Writing, playing and copying never need an account • Sign in with Apple or Google only to publish or like • Delete your account from inside the app, any time SWOOP PRO • A profile page — your picture and a grid of your work • Clean recordings, without the Swoop mark • Sign a recording with your avatar and username • Backdrops for recordings • Post a component without handing over the source Writing, playing, copying and publishing stay free.
